}
}
But now i have the function is send file. So i have to use ObjectInputStream and Object OutputStream .The problems is 2 type difference between DataInputStream,DataOutputStream and ObjectInputStream,OutputStream.How can i put thread of ObjectInputStream and ObjectOutputStreadm to my class. thanks you!
